  • Text template or tool for documentation of computer configurations

    - by mjustin
    I regularly write and update technical documentation which will be used to set up a new virtual machine, or to have a lookup for system dependencies in networks with around 20-50 (server-side) computers. At the moment I use OpenOffice Writer with text tables, and create one document per intranet domain. To improve this documentation, I would like to collect some examples to identify areas where my documents can be improved, regarding general structure and content, to make it easy to read and use not only for me but also for technical staff, helpdesk etc. Are there simple text templates (for example for OpenOffice Writer) or tools (maybe database-driven) for structured documentation of a computer configuration? Such a template / tool should provide required and optional configuration sections, like 'operating system', 'installed services', 'mapped network drives', 'scheduled tasks', 'remote servers', 'logon user account', 'firewall settings', 'hard disk size' ... It is not so much low-level hardware docs but more infrastructure / integration information in these documents (no BIOS settings, MAC addresses).

  • Windows undetectable after interrupted chkdsk

    - by Felthragar
    I have a computer that is running Windows XP. For some reason, the other day it wouldn't start giving me the following message: "ntoskrnl.exe is missing or corrupt" So I put the XP disc in the tray and fired up the repair console and ran the following: chkdsk /r It was on for about eight hours and it got to about 52% I believe. Then there was a power outage and the computer shut down (obviously). Today when I was booting it, it isn't even detecting there's an OS anymore. If I boot the computer with no cd in the tray it says: "Reboot and select a proper Boot device or Insert Boot Media in selected Boot device and press a key" If I run the repair console, or the xp installation program it isn't finding any OS installations. Any ideas on what to do next? Any help is appreciated. Thanks! Update: After turning boot-time diagnostics on, I got this message when booting without cd (instead of the previous one): "Couldn't open drive multi(0)disk(0)rdisk(0)partition(2)"

  • Resizing a System Partition Windows Server 2003 VM (Getting GParted Error)

    - by Dina
    I am getting an error while trying to resize System Partition for Windows 2003 Server (this is a VM on a Hyper-v Windows Server 2008) using GParted Live CD ISO. Followed this tutorial: http://malaysiavm.com/blog/how-to-resize-windows-2003-server-virtual-disk-on-vmware-esx/ and GParted Doc http://gparted.sourceforge.net/larry/resize/resizing.htm (They are very similar) The VM has a Dynamic VHD file, I have already increased it using Hyper-v. GParted doesn't give any clues or details for the error. Just simply errors when trying to grow the partition. Any ideas what I can do? Thanks! Using version of Gparted: gparted-live-0.13.1-2

  • Dummy SMTP server as a service

    - by levidos
    I have a Windows Server 2008 machine with IIS installed which is hosting a webapp that is sending some notification mails once-in-a-while. What I'd like to do is to monitor the email sent by the application. For this I need a dummy SMTP server which intercepts messages but won't send them further but save them locally on the hard disk. I've already found some of them like Papercut, SMTP4Dev. The problem with these that I have to be logged on the server all the time which is not suitable because the server has only 2+1 TS connections. I like to run a program like these as a windows service and check the mails when I need them.

  • DNS resolution problems; dig SERVFAIL error

    - by JustinP
    I'm setting up a couple of dedicated servers, and having problems setting up my nameservers properly. One of these is a LEMP server (LAMP with nginx in place of Apache), and the other will function solely as an email server, running exim/dovecot/ASSP antispam (no Apache). The LEMP server is CentOS 5.5, with no control panel, while the email server is CentOS 5.5 as well, with cPanel/WHM. So, I've had problems getting DNS set up properly. I have two domains, each one pointing to one of these servers. The nameservers are registered correctly with the domain registrar, and the nameserver IPs are entered correctly as well. I've spoken to tech support at the registrar and they confirm that everything is set up on their end. Not knowing much about DNS, I googled nameservers and DNS until I nearly went blind, and spent hours messing with the configuration. Eventually, I got the LEMP server's DNS working properly (no cPanel). Pleased with this triumph, I'm trying to mimic that configuration and repeat the process with the email server, and it's just not happening. The nameserver starts and stops, but the domain doesn't resolve. Things I have tried Going through standard procedures to set up DNS in WHM Clearing all DNS information, uninstalling BIND, then reinstalling all of that and again going through WHM procedures for setting up DNS Clearing all DNS information, and setting up BIND via shell (completely outside of cPanel) by using my config and zone files from the LEMP server as a template named runs just fine, but nothing is resolving. When I "dig any example.com" I get a SERVFAIL message. Nslookups return no information. Here are my config and zone files. named.conf controls { inet 127.0.0.1 allow { localhost; } keys { coretext-key; }; }; options { listen-on port 53 { any; }; listen-on-v6 port 53 { ::1; }; directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; memstatistics-file "/var/named/data/named_mem_stats.txt"; // Those options should be used carefully because they disable port // randomization // query-source port 53; // query-source-v6 port 53; allow-query { any; }; allow-query-cache { any; }; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; view "localhost_resolver" { match-clients { 127.0.0.0/24; }; match-destinations { localhost; }; recursion yes; //zone "."

Tech support is very responsive, and largely useless. Hours go by with them asking me questions to narrow down what could be wrong, then they pass the ticket to the tech on the next shift, who ignores everything that's happened already and spend his whole shift asking all the same questions the last guy asked. So, in summary: *Nameservers, with IPs, are correctly registered with domain registrar *named is configured and running *...and must not be configured correctly, because nothing resolves. Any help would be great. I changed domains and IPs in the files to generics, but let me know if you need to know the domain in question. Thanks! UPDATE I found that I didn't have 127.0.0.1 in /etc/resolv.conf, so I added it, along with my two public IPs that I have named listening on. resolv.conf search www.example.com example.com nameserver 127.0.0.1 nameserver 7.8.9.10 ;Was in here by default, authoritative nameserver of hosting company nameserver 1.2.3.4 ;Public IP #1 nameserver 1.2.3.5 ;Public IP #2 Now when I DIG example.com from the host, it resolves. If I try to DIG from my other server (in the same datacenter), or from the internet, it times out or I get SERVFAIL.

  • Ubuntu hang, and cannot be soft-reset after resuming from stand by mode

    - by Phuong Nguyen
    I have downgrade my xorg drivers, so I can hibernate and stand by my ubuntu smoothly. However, in some case, there's a problem. My ubuntu get hang. When I tried to switch to console mode (Ctrl+Alt+F1), then I cannot login. The system always reply with an error whenever I tried to press a key. When I press Ctrl+Alt+Del to perform a softreset, here what's it said: [80141.320122] end_request: I/O error, dev sda, sector 193687181 init: control-alt-delete main process (5660) terminated with status 2. This error is not even recorded in syslog. I guess this should be a problem with my hard disk since it said something about a bad sector. Exactly, what kind of error is this?

  • Cloning a linux system from sdx to cciss

    - by churnd
    I have an HP ML 310 server running CentOS Linux 5.5. I'm buying a RAID card (LSI 9260-8i) to set up a mirrored OS drive. Right now, the boot drive is set up with GRUB installed on the MBR of /dev/sda & has a 100MB /boot partition for /dev/sda1, then the rest is configured in LVM with a 20GB with a 20GB VG for the root partition & ~80GB VG for home. The new disk sizes will also be slightly larger as well. What is the best way to clone the boot drive to the new CCISS device?

  • ubuntu fails to start

    - by miccaman
    I have a laptop with ubuntu 9.10 which fails to start, and I want to copy the data from it to an external hard disk. I can login in recovery mode command line, but then I cannot mount the external hard drive. (in recovery mode I cannot write to the laptops hard drive) If I boot from an portable USB with mintlinux, I can mount the external harddrive, and copy most of the data from the laptop, however there is a dir which I have no rights to access under /home/user/Documents then I get a permission denied error. Are there any other options?

  • Which built-in account is used for Anonymous Authentication in IIS 7?

    - by smwikipedia
    We know that Microsoft IIS 7.0 offer a slew of authentication methods such as Anonymous Authentication, Form Based Authentication, Digest Authentication, etc. I read from Professional IIS 7 published by Wrox that: When we use Anonymous Authentication, the end-user does not supply credentials, effectively mak- ing an anonymous request. IIS 7.0 impersonates a fixed user account when attempting to process the request (for example, to read the file off the hard disk). So, what is the fixed user account impersonated by IIS? Where can I see it? If I don't know what this account is, how could I assign proper permissions for the clients who are authenticated as anonymous users? Thanks.

  • How do I make the Windows low memory warning less sensitive?

    - by Stephen
    I keep getting this annoying low memory warning/prompt to close games I play. It happens very often and I still have ~6 gigs of ram free. I disabled virtual memory because it was putting stuff on the pagefile when I had 10 gigs free ram so that spiked my disk usage. Is there any way to disable this warning? I have 16GB ram so it shouldn't be an issue. I would prefer to keep pagefiles off because my HD is very loud so it's nice to keep it spun down as much as possible. I don't want to disable it completely. Ideally, I would like it to go off when I have ~2GB left rather than 6, but if this isn't viable, I may just disable it completely.

  • win2008 R2 server core software RAID

    - by shimonyk
    I am trying to set up software raid on a win2008 R2 server core. I have the disks configured as dynamic. In the server manager gui, i can see the disks, but when i right click, the option to set up "new mirrored volume" is not listed. I tried it with the command line using diskpart, and it gives the error "Virtual Disk Service Error: The size of the extent is less than the minimum." The drive are a new pair of 1Tb disks. Is this not supported in server core, or am i missing something else? Thank you

  • Possible to use DRBD on two ESXi virtualized servers?

    - by chen
    I have two servers (attached disks have been set up as hardware RAID1 for disk device level failure resilience). Here is the setup in my mind: 1) Install ESXi on each of the physical server, M1, M2; 2) Start one VM on each of the ESXi virtualized physical server V1, V2; 3) Install the DRDB drivers within V1 and V2. Essentially, this is a "virtualizing machine running DRBD in the VM's instead of bare metal hardware" idea. My question is whether the above setup can achieve the same "networked RAID1" goal that DRDB can achieve in the bare-metal physical machines (http://www.drbd.org/). Thanks. [EDIT] I found this (http://serverfault.com/questions/49305/drbd-experimentation-and-virtualization) is a similar question, but the answer does not seem to be firmative enough for me to follow.

  • Which software to use for RAMDISK on Windows 2008?

    - by Tony_Henrich
    I am building a server machine with lots of RAM. At least 16G. I am planning to put my frequently read and written data in RAM so I am looking for software for creating RAM disks. This is for Windows Server 2008 R2 Standard 64bit. Any recommendations? I would like one where I can flush the disk image into persistent storage upon demand. For example when Windows shuts down. (I am aware of all the consequences of data loss when power is lost)

  • One hard drive missing after converting from ide to ahci

    - by user700859
    I have two 500GB SATA HDD in my desktop running XP. After converting from IDE to AHCI, the HDD I use to store data can no longer be accessed from XP. It shows only the first partition as 150GB, and data type is listed as RAW. However, if I boot into a live linux environment or if I pull that HDD out and connect it using USB, I can still get to all my files again. So I completely formatted the HDD into one single partition. But XP still does not recognize it. It still shows the disk as the 150GB partition and data type is still RAW. What's going on and how do I fix this? Thanks in advance.

  • (Preferably) Encrypted Server Backups

    - by Shoaibi
    I have somehow managed to purchase a VPS after collecting money for sometime, now problem is i cant find a way to backup the server. My previous approach was: Got a webdav account from mydisk.se, mounted it on the vps, used duplicity and created encrypted backups. Problem is it was only 2G, and its running out of space, at my own place i dont have a stable internet connection else i have a 500G drive that i could surely use for backups. The vps has a 12G HD, and i would like to backup /home, /root, /etc, /var/ (specially log and www). Any ideas are welcomed. [EDIT] I am more of looking for resource of setting up a backup-point or such(i know how to setup a backup server, but i cant as i dont have stable connection or the money to buy another VPS/disk for backup) , i have already got the tools needed.

  • linux/shell: change a file's modify timestamp relatively?

    - by index
    My Canon camera produces files like IMG_1234.JPG and MVI_1234.AVI. It also timestamps those files. Unfortunately during a trip to another timezone several cameras were used, one of which did not have the correct time zone set - meta data mess.. Now I would like to correct this (not EXIF, the file's "modify" timestamp on disk). Proposed algorithm: 1 read file's modify date 2 add delta, i.e. hhmmss (preferred: change timezone) 3 write new timestamp Unless someone knows a tool or a combination of tools that do the trick directly, maybe one could simplify the calculation using epoch time (seconds since ..) and whip up a shell script. Any help appreciated!

  • difference between server and desktop

    I want to set up a webserver. I would like to buy a hardware for that and i am trying to understand if i should buy a desktop and host the webserver on that or do i have to buy some used server from ebay and host on it. Example is http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180986172861&ssPageName=ADME:X:RTQ:US:1123 But what is the difference in desktop and server? These days even desktops are coming with high RAM. Only other difference i see is servers have RAID HARD disk. Is there any other difference?

  • Deleted entire harddisk. Now my laptop won't boot anything and stuck at grub rescue

    - by Jahan
    My laptop is Dell Inspiron N4030. I used to use Ubuntu 12.04 and it was on the entire hard drive. I tried to install windows 7 but my laptop couldn't install it. So, I decided to delete the entire hard drive and do a fresh install of Windows 7. But after deletion I immediately removed the gparted live usb which I was using to delete the partitions of my hard drive. And then tried booting from windows 7 cd, didn't work, tried ubuntu live cd, didn't work, tried hiren's boot cd, didn't work, tried super grub disk, didn't work. Probably I'm not doing it right. Help needed badly.

  • Windows 7 Public Documents Folder - how to move it to drive d:

    - by Bazza Formez
    Hi, I've just bought a new pc, and it is running Windows 7. I'm wanting to set up all of the documents folders such that they point to folders on a second drive partition (ie. disk D:) so that I have a nice separation of os from docs. I have managed to do this for each user on the machine (by opening up properties for documents folder and changing location). Hwoever, this procedure doesn't seem to work for the public documents folder. I cannot change the location for that one (even though I have administrator privileges). It is greyed out and cannot be changed. Any ideas ? Thanks!!

  • Is this a valid backup strategy for MongoDB?

    - by James Simpson
    I've got a single dedicated server with a MongoDB database of around 10GB. I need to do daily backups, but I can't have downtime with the database. Is it possible to use a replica set on a single disk (with 2 instances of mongod running on different ports), and simply take the secondary one offline and backup the data files to an offsite storage such as S3 (journaling is turned on)? Or would using master/slave be better than a replica set? Is this viable, and if so, what potential problems could I have? If not, how do I conceptualize this to work?

  • 32 vs 64-bit software for same machine?

    - by GorillaSandwich
    What is the difference between 32 and 64-bit software? My understanding is that 64-bit can use more RAM, if it's available, because it has a larger address space for it. Is this correct? And, specifically: If I have a 64-bit operating system with lots of RAM, and I install, say, the 32-bit version of MySQL instead of the 64-bit version, will it be unable to use all the available RAM and therefore run slower than the 64-bit version might on the same machine (assuming RAM becomes the bottleneck before processing speed or disk access speed or whatever)? If I have a 32-bit operating system and I install a 64-bit piece of software on it, will it (probably) fail to run?

  • Disable RAID Controller

    - by B.Mr.W.
    I have some decent HP Proliants server that come with "HP Smart Array P410i Controller" enabled, I am using these boxes to set up a Hadoop cluster and I know, RAID is for sure a no-no for Hadoop since the application itself will take care of data redundancy and extra intelligence provided by RAID won't be helpful and might turn down the performance. I tried to disable the devices at the BIOS and the box cannot even access the disk afterwards. So I am assuming the controller is sitting between disks and mother board, and we have to turn it on and configure it to "level0" or something like that. I am wondering what should I do to "disable" the RAID functionality so it will fit into the Hadoop environment.
